A Multiphase Operational and Environmental Assessment of Lunar Surface Habitation, Lunar Gateway Transit Systems, and Acceleration Pathways for Sustained Human Habitation of the Martian Surface

This study evaluates the operational, environmental, and habitation-system requirements for sustained human presence on the lunar surface, the performance of the Lunar Gateway as a transit and staging architecture, and the pathways required to accelerate readiness for Martian surface habitation. The protocol examines habitat resilience, radiation exposure modeling, life-support continuity, EVA logistics, behavioral health in isolated environments, and systems-engineering workflows across lunar, transit, and Mars-analog environments. Special emphasis is placed on the identification, extraction, processing, and utilization of lunar water-ice deposits as a critical resource for life-support, radiation shielding, and in-situ propellant production. Findings will inform future mission design, habitation module development, and interplanetary operational frameworks.

Inclusion Criteria: * Adults aged 18-65 * Able to participate in isolated, confined, or controlled operational environments * Prior experience in engineering, environmental systems, analog missions, or mission operations * Ability to perform EVA-analog tasks and operational workflows * Willingness to participate in multi-phase lunar, transit, and Mars-analog simulations Exclusion Criteria: * Medical or physical limitations that prevent participation in isolated or operational environments * Conditions that limit safe participation in EVA-analog tasks * Inability to comply with operational protocols or safety requirements * Participation in conflicting operational studies
